My buddy recently acquired a 14 bolt from a junk yard for $130. We repainted it, bought new rims, mounted the tires and bought the conversion u-joint. As we roll the axle under his Blazer, I notice something just doesn't seem right! The spring perches are too far apart! I'm thinking, "What the heck! This should be a direct bolt in, unless....... it's an axle from a 3/4 ton van." Sure enough the axle is too wide! As the frustration of such an immense screw up begins to set in I begin to wonder why I didn't put in a lottery ticket! The chances of finding a 14 bolt from a 3/4 ton van around my area is second to none! And the worst thing is, I knew about the difference between the van and truck axle and didn't even bother to take measurements, as I did mine, before I helped him take it from the junk yard! Boy do I feel like a jackarse! Just a word of advice, take measurements! If the spring perches are in the right place, it's a direct bolt in. If the perches are not in the right place, it's the wrong 14 bolt! My friend didn't bash me enough to feel good about myself. So, go right ahead and let loose! If it breaks, it wasn't good enough!
